4. Historic Scotland- Information about the properties cared for by Historic Scotland, as well as Scotland's "listed buildings" and "scheduled ancient monuments". This site contains practical information for visiting the different properties.

5. Trip Advisor- The forum for Scotland is as friendly and helpful as one that I used extensively for our trip to Ireland. Before posting a question, be sure to search the archives. It is possible that someone else has already asked and received answers to the same question. By reading the archives, you can also find new travel ideas. I always look for off the beaten path suggestions from locals or travelers who have recently returned from the place we are going to.

Now I just need to narrow down all the options available to us and create a fantastic list of things to do. That's all. No problem. We just need to plan a two year trip.
